Leading culture change at scale.

The CEOs who succeed at culture change have, in our experience, an unusual relationship with their own behaviour. They understand that the values statement is decoration; the lever is the set of decisions they are visibly making about who gets promoted, what behaviour they tolerate, and where they spend their own time. Below is the picture we draw for leaders starting a serious culture-change effort.

Culture is not a deliverable

The first instinct of most leadership teams is to treat culture as a programme — workshops, town halls, a values statement, a launch event. Expect results in a year. By year three, that script has reliably failed. What works instead is much harder to package: culture is the residue of decisions. The poster on the wall is decoration. You change the culture by being unambiguous, repeatedly, about which behaviours win.

The timeline is longer than the board wants

In a large organization, plan for three to five years for any meaningful shift, and seven to ten years for it to feel native to a new hire. Leaders who claim they changed the culture in eighteen months changed the slogan. The reality is much slower, and the CEO has to be at peace with that. If the board cannot tolerate that timeline, the culture change will not happen — they will replace the CEO before it lands. The board conversation about timeline is the most important early conversation in any serious culture programme.

Promotions are the most underrated lever

People watch who gets promoted with extreme attention. A statement that says "we value collaboration", followed by the promotion of a brilliant but corrosive individual contributor, sends a single message: "we say collaboration but reward something else." Three of those decisions and the values statement is dead. Three counter-examples — promoting the collaborative person over the higher-output but corrosive one — and the message starts to land.

The people who do not fit the new direction

The temptation is to wait. Hope they will adapt. Find a sideways move. They almost never adapt. Every quarter you keep a senior leader who does not embody the direction, you signal to everyone else that the direction is optional. The conversations are uncomfortable; doing them late is worse than doing them early.

The middle layer is decisive

Culture change that wins at the top and loses in the middle does not stick. The most consequential audience is the layer of leaders two reports below the CEO — group heads, mid-level operating leaders. They translate intent into practice. If the CEO has not personally convinced them, the rest of the organization will not be convinced either. Spend disproportionate time there.

What travels between sectors and what does not

The diagnostic travels — who is winning, who is losing, what behaviours are getting rewarded, where the energy is concentrated. The interventions do not travel cleanly. What works in a fast-moving consumer business — symbolic resets, town halls, visible promotions — does not translate to a regulated financial-services firm, where the entire workforce reads the supervisory news every morning. Leaders who try to import the playbook from their last company tend to alienate everyone in the first six months.

What boards should be asking in year one

The metrics boards want — engagement scores, retention, eNPS — lag by 18 to 24 months. Boards that ask, in year one, "where is the engagement-score improvement?" are asking the question that cannot yet be answered. The right question in year one is: is the CEO making decisions that are consistent with the stated direction? If yes, hold the line. If no, replace the CEO. Waiting for year-one metrics is a category mistake.

Where external help actually adds value

In two narrow places. First, diagnostic work that the internal team cannot do credibly — the honest read on where the culture is, what people actually believe, what the senior team's blind spots are. Second, designing the structural levers — performance management, promotion criteria, compensation — where someone with pattern recognition across other companies adds real value. Outside that, we are sceptical. Culture change is the CEO's job. Anyone who tells you they will lead it on your behalf is selling something they cannot deliver.

One thing to do in the first hundred days

Make three highly visible decisions in the first hundred days that signal what the new direction actually means. Not a launch event — three decisions. Promote someone counter-stereotypically. Move on a senior leader who does not fit. Cut a programme that everyone knows is symbolic of the old way. The organization will read those three decisions for years and reference them every time someone tries to drift back. If you do not have three decisions you are willing to make in the first hundred days, you are not yet ready to lead the change.
